Rolex Datejust 31 Yellow Rolesor — Champagne Roman Dial, Fluted Bezel | Ref. 178273

The Datejust 31 in Yellow Rolesor has long been the quintessential dress watch for those who favour the warmth of gold without abandoning the durability of steel. Reference 178273 embodies this philosophy with characteristic Rolex restraint: a 31 mm Oyster case in Oystersteel paired with 18ct yellow gold crown guards, bezel, and Jubilee bracelet links, all capped with the classically fluted bezel that Rolex has produced since the 1940s. The champagne dial with Roman numeral hour markers provides a rich, antique-inflected backdrop that pairs effortlessly with both formal and casual dress.

The 178273 is driven by the Calibre 2235 automatic movement, a self-winding workhorse featuring Rolex's Parachrom blue hairspring — an alloy of niobium and zirconium that is ten times more shock resistant than traditional hairsprings and impervious to magnetic fields. Oscillating at 28,800 vph with a power reserve of approximately 48 hours, the movement is Superlative Chronometer certified to ±2 seconds daily accuracy. The Oyster case maintains water resistance to 100 metres.

For collectors, the Yellow Rolesor Datejust 31 with fluted bezel and Roman numeral dial occupies comfortable territory as both a daily companion and an appreciating asset. The 178xxx series represents the final generation before Rolex's transition to the 278xxx calibre update, making well-preserved examples increasingly appealing to those who value continuity with Rolex's mid-size heritage. The champagne Roman dial variant, in particular, is sought for its timeless aesthetic that transcends fashion cycles.
